The invention belongs to the field of optical detection, and particularly relates to a glass full-size warping evenness detection device and detection method. The glass full-size warping evenness detection device comprises a rack, a conveying module, an illumination module, an imaging module, a camera module and an imaging processing module, wherein when detection begins, a to-be-detected sample is only needed to be placed at the front end of the conveying module, so that full-size warping flatness detection can be carried out under driving of the conveying module; and in a detection process,participation of workers is not needed, so that a large quantity of manpower and material resources is reduced, the working efficiency is high, a quality project of wrapping unevenness in a glass production technological process can be monitored and detected in real time, the aim of inspecting the glass one by one is fulfilled, comprehensive detection can be carried out, missed detection is avoided, detection accuracy is high, output of defective products is reduced, quality and using performance of the to-be-detected sample are improved, manpower used in random inspection and a process in theexisting detection process can be greatly improved, and detection result data can be fed back in real time in a detection process, and production staffs and quality detection staffs can do effectiveand real-time disposal according to a feedback result, so that the working efficiency is improved.
